暂无补丁情况
官方补丁披露时间
2022-11-10漏洞描述
A flaw was found in Kubernetes, where users may have access to secure endpoints in the control plane network. Kubernetes supports node proxying, which allows clients of kube-apiserver to access endpoints of a Kubelet to establish connections to Pods, retrieve container logs, and more. While Kubernetes already validates the proxying address for Nodes, a bug in the kube-apiserver made it possible to bypass this validation. Bypassing this validation allows authenticated requests destined for Nodes to redirect to the API Server through its private network.解决建议
建议您更新当前系统或软件至最新版，完成漏洞的修复。
